UART only works while ST-Link is connected
I'm using an ST-Link broken off from a NUCLEO board to program a custom board with an STM32G4A1 on it. The issue is that UART transmission only seems to work while the ST-Link is connected - probing the line with a scope shows no activity when the ST...
Help Needed: Issues Programming and Communicating via USB after PCB Redesign (STM32F429ZIT6)
Hello everyoneI've hit a bit of a snag with my PCB redesign (V2) featuring an STM32F429ZIT6. While the initial version (V1) worked like a charm, some layout changes and component swaps (SN74ABT16245ADL to two SN74HCT245DWR) in V2 are causing issues w...
Resolved! Flash erase stall on STM32H753 and servicing an external watchdog
Hi,I need to service an external watchdog when a flash sector is being erased. The sector being erased is in the same flash bank where code is executed from. Before I try to jump and run from RAM I had a few questions.Where is flash stall discussed...
Resolved! LTDC problem
Hello,i have problem with custom board assembled with STM32F767BIT6. I'm trying to interfacing LCD-TFT DEM 800480K3 TMH-PW-N which is assembled by HX8264E, HX8664B drivers. I'm using RGB888 interface configured via STMCubeIDE filled by resolution 800...
No trigger of HRTIM burst DMA controller
Hi,I want to update multiple HRTIM registers with a single DMA request on a STM32G474RE. To do this, I am trying to follow this simple Getting started with HRTIM tutorial, which has a section "#To_go_further_about_DMA_burst" on the board "B-G474E-DPO...

Store data in internal flash without erasing whole page
Hi, I would like to know method and sample code storing data without erasing whole memory page. I do refer example FLASH_EraseProgram, but i have wrote program that almost finish up the flash memory, if i erase a page, a 2KB page, it will erase my co...
Failed to trigger STM32L431 USART1 bootloader via SW
Hi guys,I could set MCU into bootloader mode manually by using PH3/Boot0, but I can't get trigger bootloader via SW... I did check previous posts, but somehow it does not help.HW setup: I have dev board with STM32L431. It has USART1 (PA9, PA10) conne...
Resolved! Not a genuine ST Device!
HiI would like to debug STM32F303RDT6 using a combination of Keil and ULINK2.When I start debugging on the target microcontroller (STM32F303RDT6), **Not a genuine ST Device! Abort connection** is output as shown below.We investigated the cause.I foun...
